The Nearest Stars to Earth (Infographic) The nearest stars to Earth are in the Alpha Centauri triple-star system, about 4.37 light-years away. One of these stars, Proxima Centauri, is slightly closer, at 4.24 light-years. Of all the stars closer than 15 light-years, only two are spectral type G, similar to our sun: Alpha Centauri A and Tau Ceti. The majority are M-type red dwarf stars.

Closest Star to the Sun You might have heard that it’s Alpha Centauri, the third brightest star in the sky, just 4.37 light-years from Earth. But Alpha Centauri isn’t one star, it’s a system of three stars. First, there’s a binary pair, orbiting a common center of gravity every 80 years.

StarChild Question of the Month for May 2000 The star is 25,000 light-years away from Earth. Despite this great distance, the star would be visible to the naked eye if it were not for all the dust between it and the Earth. UPDATE! As of January 2009, we now know about some other really big stars. One is called Eta Carinae.

The 10 Closest Stars to Earth Ross 248, about 10.32 light-years form Earth, is actually moving so fast that in about 36,000 years it will actually take over the title as the closest star to Earth (besides our Sun). However, it will quickly begin moving away again and will relinquish the title about 9,000 years later.oss 248, about 10.32 light-years form Earth, is actually moving so fast that in about 36,000 years it will actually take over the title as the closest star to Earth (besides our Sun).

Alpha Centauri system, closest to sun Alpha Centauri is the nearest star system to our sun at 4.3 light-years away. That’s about 25 trillion miles (40 trillion km) away from Earth – nearly 300,000 times the distance from the Earth to the sun. How might we travel to Alpha Centauri, the next-nearest star? And how long would it take to get there? Follow the links below to learn more.

- The very nearest galaxy would be one of the small satellite galaxies. There are about 50 galaxies within about 1.4 million light years of the Milky Way. The closest are about 1000 light years from the edge, which by our reckoning would be about 63000000=6.3×107 AU from the edge. Perhaps of more interest is the distance to the Andromeda galaxy, our largest neighbour in the Local Group.

- This map shows all the star systems that lie within 12.5 light years of our Sun. Most of the stars are red dwarfs-stars with a tenth of the Sun's mass and less than one hundredth the luminosity.Roughly eighty percent of all the stars in the universe are red dwarfs, and the nearest star-Proxima-is a typical example.his dim red dwarf is the nearest star to the Sun, and it is a member of the Alpha Centauri system despite lying 0.24 light years from the main pair of stars, requiring over one million years to orbit them. Proxima was discovered in 1915 by Robert Innes and was at that time the least luminous star known.

- This depends on how fast you are travelling. The nearest star to our solar system is Proxima Centauri, which is located 4.2421 light years away (or 40,133,364,737,735km). The … fastest man-made object to date is the Helios 2 solar probe, which had a speed of 252,800km/hr.

What is the closest solar system? Alpha Centauri is the closest star to our solar system, at about 4.2 Light Years.. It's not a solar system in the sense that ours is though - it's a triple star system composed of Alpha Centauri A (a little bigger than the Sun), Alpha Centauri B (a little smaller than the Sun) and Proxima Centauri (a red dwarf - very small star).

List of nearest terrestrial exoplanet candidates The nearest such planet may be 12 light-years away, according to the scientists. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone of Proxima Centauri, the closest star to Earth. Called Proxima b, the planet is 1.3 times the mass of Earth and has an orbital period of roughly 11.2 Earth days.

Gliese 581c In astronomical terms, the Gliese 581 system is relatively close to Earth, at 20.3 light years (192 trillion km or 119 trillion miles) in the direction of the constellation of Libra. This distance, along with the declination and right ascension coordinates, give its exact location in our galaxy. It is identified as Gliese 581 by its number in the Gliese Catalogue of Nearby Stars; it is the 89th closest known star system to the Sun.

How far away are the stars and galaxies? How are these distances calculated? Many of us, while still in grade school, learned about the staggering distances to planets, stars and galaxies. The sun is approximately 150 million km or 93 million miles away, a distance that is known as the astronomical unit (AU). Venus, our closest neighbor, is 0.72 AU from the sun, while Mars is 1.52 AU from the sun.

How fast was Voyager 2 going when it left our solar system, and, at that speed, how long to the closest star? Best Answer: At present, the Voyager I & II are moving at a speed of 35,000 miles per hour. The nearest star, Proxima centauri is 4.22 light years away. Light travels at a speed of 186, 000 miles/sec. 186,000 x 3600 x 24 x 365 = 5.865 trillion miles per light year.

- Antares is a red supergiant star at a distance of 550 light-years! (August 24, 2016, 10:00 pm EDT) On August 27, Venus and Jupiter are only 0.07°, or 4.2 arc-minutes, apart. This is about 1/7 the width of the Full Moon! This is the closest appulse – or close approach of two planets to each other - in 2016. As seen here, Venus will appear to be closer to Jupiter than one of Jupiter's large moons: Callisto.
